不同温度和盐度对大竹蛏耗氧率和排氨率的影响
Studies on the effect of temperature and salinity on oxygen consumption and ammonia excretion in the grand jackknife clam Solen grandis
摘要
Abstract
Temperature and salinity are the main factors affecting the metabolism of aquatic biological organisms, and these environmental factors vary seasonally. This study investigated the effects of temperature and salinity on oxygen consumption and ammonia excretion of the grand jackknife clam Solen grandis. The experimental setup included a temperature gradient (12, 17, 22, 27, and 32℃) and a salinity gradient (12, 17, 22, 27, and 32). The re-sults demonstrate that temperature has a significant effect on oxygen consumption and ammonia excretion rates in this strain (P < 0.05). As the temperature increased, oxygen consumption and ammonia excretion first decreased and then increased. The lowest oxygen consumption rate is 1.571 mg/(g·h) at 32℃, and the lowest ammonia excretion rate is 0.127 mg/(g·h) at 17℃. As salinity increased, oxygen consumption first increased and then decreased, whereas ammonia excretion first decreased and then increased. The highest oxygen consumption rate is 3.106 mg/(g·h) for a salinity value of 22, and the lowest ammonia excretion rate is 0.145 mg/(g·h) for a salinity value of 27. At 12℃, the O︰N ratio ranged from 4.378 to 16.755 as the salinity value increased from 12 to 32. At a salinity value of 32, the O︰N ratio ranged from 5.525 to 79.037 as the temperature increased from 12℃ to 32℃. The information re-garding its response to different temperature and salinity values has implications in the S. grandis aquaculture industry.关键词
